Quantum gravity and unification
„Quantengravitation und Vereinheitlichte Theorien“
General relativity theory and the standard model of particle physics describe physical phenomena correctly over a vast range of distances and are nevertheless incomplete. In order to understand what is happening inside a black hole or at the Big Bang, a new unified theory is sought which contains the standard model and the theory of gravitation as limiting cases, but whose mathematical contradictions are overcome. Maybe reflections on symmetry can help here.
